Inspiring Action for Nonpoint Source Pollution Control: A Manual for Water Resource Protection
Nelson, P., M. Davenport and T. Kuphal. 2017
Inspiring Action draws upon decades of engagement in conservation management and years of applied research on conservation behavior. Its guiding principles for inspiring conservation action not only are backed by the latest social science, but also have been field-tested in Minnesota. Conservation resource professionals will find the statistics, stories, and strategies presented useful in project design and evaluation, as well as for leveraging support for conservation programming. The manual describes a new approach for water resource protection informed by systems thinking and a model of community capacity. It then offers real-world examples and success stories based on the authors’ ongoing work in Minnesota.
Prediction of lake water temperature, dissolved oxygen, and fish habitat under changing climate
Missaghi, S., M. Hondzo and W. Herb.
Springer Science+Business Media Dordrecht
We applied a three-dimensional lake water quality model to investigate the influence of local meteorological conditions on fish habitat under one historical and two future climate changes scenarios. Compared to the historical normal climate scenario, the averaged surface water temperature increases up to 4 °C and the dissolved oxygen concentration is 1 mgL−1less during the ice-free seasons under the future climate scenarios.
Effect of nonreactive kaolinite on 4-chloronitrobenzene reduction by Fe (II) in goethite–kaolinite heterogeneous suspensions
Strehlau, J.H., J.D. Schultz, A.M. Vindedahl and W.A Arnold
Environmental Science 2017
The kinetics of model contaminant 4-chloronitrobenzene (4-ClNB) reduction by Fe (II) in aqueous suspensions containing either or both goethite (α-FeOOH) nanoparticles and
kaolinite (Al2Si2O5 (OH) 4) were quantified to elucidate the effects of nonreactive clay minerals on the attenuation of nitroaromatic groundwater contaminants by iron oxide nanoparticles.
Optical and Photochemical Data of Prairie Wetlands collected in North Dakota and Minnesota from 2012-July to 2014-November
MaCabe, A. and W. Arnold - 2017
Surface water samples were collected from seven prairie pothole wetlands between 2012-
July and 2014-November. Optical and photochemical parameters of the samples were
measured under controlled laboratory conditions. The data was collected to better
Stormwater management and Climatic Change: Vulnerability and Capacity for Adaptation in Urban and Suburban Contexts
Moore, T.L., J.S. Gulliver, L. Stack and M.H. Simpson
Climatic Change, 138, 491-504, 2016.
Managing stormwater under climate uncertainty is a concern in both built-out communities and those continuing to undergo land use change. In this study, a suite of climate change scenarios were developed to represent a probable range of change in the 10-year recurrence interval design storm.
Contribution of leaf litter to nutrient export during winter months in an urban residential watershed.
Bratt, A.R., J.C. Finlay, S.E. Hobbie, B.D. Janke and A.C. Wor
Environmental Science & Technology 2017
Identification of non-point sources of nitrogen (N) and phosphorus (P) in urban systems is
imperative to improve water quality and better manage eutrophication. Winter contributions
and sources of annual N and P loads from urban watersheds are poorly characterized in
Permeable pavement in northern North American urban areas: research review and knowledge gaps
Weiss, P.T., M. Kayhanian, J.S. Gulliver and L. Khazanovich
International Journal of Pavement Engineering, In Press, 2016.
A majority of existing permeable pavement installations are related to parking lots and commercial areas with low speeds and light traffic loads. During the past two decades, a tremendous amount of progress has been made with regard to the application of permeable pavements regarding mix design, hydrologic design, water quality assessment and maintenance requirements.
Successful Resolution of Recurrent Clostridium difficile Infection using Freeze-Dried, Encapsulated Fecal Microbiota; Pragmatic Cohort Study
Staley, C., M.J.Hamilton, B.P Vaughn, C.T. Graiziger, K.M. Newman, A.J. Kabage, M.J. Sadowsky, and A. Khoruts
American Journal of Gastroenterology 2017
Fecal microbiota transplantation (FMT) is increasingly being used for treatment of recurrent Clostridium difficile infection (R-CDI) that cannot be cured with antibiotics alone. In addition, FMT is being investigated for a variety of indications where restoration or restructuring of the gut microbial community is hypothesized to be beneficial. We sought to develop a stable, freeze-dried encapsulated preparation of standardized fecal microbiota that can be used for FMT with ease and convenience in clinical practice and research.
Effective Impervious Area for Runoff in Urban Watersheds
Ebrahimian, A., J.S. Gulliver and B.N. Wilson
Hydrological Processes, 30, 3717-3729, 2016.
Effective impervious area (EIA), or the portion of total impervious area (TIA) that is hydraulically connected to the storm sewer system, is an important parameter in determining actual urban runoff. EIA has implications in watershed hydrology, water quality, environment, and ecosystem services. The overall goal of this study is to evaluate the application of successive weighted least square (WLS) method to urban catchments with different sizes and various hydrologic conditions to determine EIA fraction.
Infiltration Capacity of Roadside Filter Strips with Non-Uniform Overland Flow
Garcia-Serrana, M., J.S. Gulliver and J.L. Nieber
Journal of Hydrology, 545, 451-462, 2017.
The side slope to a roadside swale (drainage ditch) constitutes a filter strip that has potential for infiltration of road runoff, thereby serving as a stormwater quantity and quality control mechanism. A total of thirty-two tests were performed during three seasons in four different highways located in the Minneapolis-St. Paul metropolitan area, MN to analyze the infiltration performance of roadside filter strips and the effect of fractional coverage of water on infiltration.
Institute Profile: The Large Lakes Observatory and the Scientific Study of the Large Lakes of Earth
Robert Sterner, Steve Colman and Thomas Johnson 2017
Bulletin Limnology and Oceanography
LLO (Large Lakes Observatory) houses the necessary infrastructure and maintains the expertise needed to conduct state-of-the-art research on these vast inland seas. LLO scientists have carried out major expeditions to the great lakes of the East African Rift Valley, Lake Issyk Kul in central Asia, Lake Nicaragua, Lake Qinghai in China, Great Slave Lake in the Canadian Arctic, as well as to smaller lakes throughout the world. At the same time, Lake Superior as headwaters of the Laurentian Great Lakes continues to be a focus. The combination of its oceanographic approach and its global perspective on large lakes makes LLO unique among limnological research institutes in the world.
The Minnesota Technical Assistance Program is actively seeking six metro-area businesses to host summer intern projects aimed at water conservation. A water conservation focused intern is a great opportunity for your facility to address complex issues like water balances, water optimization, sewer access or strength charges, and water/energy costs.
